Frequently Asked Questions
Quick answers about privacy, supported files, and how the tools behave in your browser.
Do you upload my files?
Many tools run locally in your browser. Your files are typically processed in-memory and then downloaded. If a tool requires a server-side component, it should be clearly stated on that page.
Why does a tool feel slow?
Browser processing depends on CPU, RAM, and file size. Scanned PDFs with many images are heavier than text PDFs.
Will my PDF quality change?
It depends on the tool. Page reordering/merging usually preserves quality. Compression can reduce overhead; heavy image recompression is not always performed.
Which browsers work best?
Modern versions of Chrome, Edge, Firefox, and Safari typically perform best. Keep your browser updated.
Can I use it on mobile?
Yes for many tasks, but very large files may exceed mobile memory limits. Desktop is recommended for large PDFs.
Where can I request features?
Use the Contact page and include the tool name and the exact workflow you want.
More answers (based on real workflows)
Is there a maximum file size?
Browser tools are limited by your device memory and the browser itself. If a large file fails, try desktop, close other tabs, and process fewer pages (extract pages first).
Do you keep copies of my files?
When tools run locally, files stay on your device and are processed in-memory. Downloads are generated in your browser. If a page ever requires server-side processing, it should clearly state that upfront.
Why does a “scan” PDF stay big?
Scans are images. File size is driven by resolution (DPI), color depth, and compression. Best results come from exporting at the right DPI and then compressing.
Can I use the tools for sensitive documents?
Local processing is designed for privacy. Still, always verify output before sharing and avoid uploading sensitive files to third-party services unless you trust them.
What if the output looks different?
Structure-preserving tools (merge/split/reorder/delete pages) should not change visual quality. Converters and compressors may simplify complex layouts. Always open the result and spot-check.
How do I report a bug?
Use the Contact page and include the tool URL, browser, OS, file size/page count, and steps to reproduce. Do not email confidential files; use a sample.
